Bug 878763 (CVE-2022-41973, CVE-2022-41974) – <sys-fs/multipath-tools-0.9.3: multiple vulnerabilities

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description John Helmert III 2022-10-30 01:26:23 UTC]

CVE-2022-41973 (https://bugzilla.suse.com/show_bug.cgi?id=1202739):

multipath-tools 0.7.7 through 0.9.x before 0.9.2 allows local users to obtain root access, as exploited in conjunction with CVE-2022-41974. Local users able to access /dev/shm can change symlinks in multipathd due to incorrect symlink handling, which could lead to controlled file writes outside of the /dev/shm directory. This could be used indirectly for local privilege escalation to root.

CVE-2022-41974 (https://bugzilla.suse.com/show_bug.cgi?id=1202739):

multipath-tools 0.7.0 through 0.9.x before 0.9.2 allows local users to obtain root access, as exploited alone or in conjunction with CVE-2022-41973. Local users able to write to UNIX domain sockets can bypass access controls and manipulate the multipath setup. This can lead to local privilege escalation to root. This occurs because an attacker can repeat a keyword, which is mishandled because arithmetic ADD is used instead of bitwise OR.

Please bump to 0.9.2.

'Reference' is not a valid GLEP 66 tag so the bot didn't tag the bug.
